What do you mean by this ? What exactly is the procedure you're using and
what are the error messages, if any ?

DXF should be ascii, no ?

I suppose AI can export to raster formats (PNG, JPG, TIFF...), so you
could try that and import the result with r.in.gdal. Then you could either
transform the raster to vector (see
http://grass.itc.it/gdp/grass5tutor/HTML/c1452.html), or use the raster as
a backdrop in v.digit and digitize on screen.
